Features
01.
Automated operation and control
- Operation nad monitoring are automated with an advanced micom-based contriller, reducing the size and weight of the equipment, meeting customers ewquirments and saving energy.
02.
Compact, light-weight design
- Newly designed heat exchangers reduced height by 20%, footprint and space by 10~30% and weight by 15~20%, compared with the previous version.
03.
Faster start-up/shut-down and dilution time
- Due to compact design and parallet flow system which reduced the volume of the solution and thermal capacity of the high remperature generator, the start-up and shut-down times are shortened. in addition the Micom controller shortened dilution operation time.
04.
Reduced steam consumption
- Steam consumption rate was lowered by 4.5% by applying high performance heat transfer tube and reducing heat exchanger area.
05.
Improvement of fuel efficiency in partial load operation
- In reduced load condition the speed of the solution pump is controlled with an inverter to reduce the solution flow in accordance with the cooling load, resulting in energy saving
06.
High reliability
- Air-tight design and vacuum test using helium gas have inproved the reiiability of vacuum capability. Reliability and stability of the equipments have been further enhanced by applying the data obtained from the performance test facilities in design.
07.
Perfect capacity control
- The steam flow control value which controls fuel flow into high temperature generator according to the coolong water temperature at outlet and temperature control function have enhanced the efficiency of partial-load operation and capacity control according to the load.
08.
Significant saving of power cost
- Power consumption could be reduced by 10% or more by optimizing the solution cycle and using high performance solution and coolant pumps. in addition , stopping the operation of the cooling water pump, refrigerant pump and cooling towr during dilution operation has further reduced power cost.
09.
Employment of special spray nozzles
- Latest, special spray nozzles are used in the evaporatir and absirber, which can spray refrigerant and solution on the entire surface of the evaporatir and absorber tubes, without bias, to improve heat efficiency. Pump power efficiency is improved by optimized design.
10.
Intorduction of new extraction system
- The hydrogen gas and non-condensable gases gernerated in the equipment are continuously extracted out using an extraction pump and micom-controlled autimatic extraction system to maintain vacuum and improve cooling efficiency.
11.
Automatic anti-crystallization system
- The density of solution is monitored with a micom to respond to the changes in operating condition. Anti-cystallization system including a service valva pervents crystallization.
12.
Perfect safety protection system
- Various safety devices protect the system from the troubles including reduced chilled water flow, low chilled water temperature, cooling water pump inerlock, high perssure in the high temperature generator, low liquid level, high temperature, pump failure, etc.
13.
Divisible design
- The entire system can be separated into lower drum(evaporator, absorber), upper drum(condenser, low temperature generator), and high temperature drum(high renoerature generator) to reduce heat transfer loss and convenience of transportation and installation.
